COB-STACKER FOR CORN-SHELLERS.

SPECIFICATION forming part of Letters Patent No. 583,649, dated June 1, 1897.

Application filed April 12,1897. Serial No- 631,789. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. KNAPP, of Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Oob-Stackers for Corn- Shellers, of which the following is a specification.

This invention is intended to furnish simplified and improved means for transmitting motion from a sheller to the cob-stacker dragbelt, while providing for swinging motion in the stacker, when such motion is desired, and for holding the stacker in any desired position with relation to the sheller. It is exemplified in the structure hereinafter described, and it is defined in the appended claims.

In its broadest sense the invention is embodied in ahorizontal sheller, a stacker-frame swung from the sheller-frame in the rear of the cylinder and below the shaft thereof, stacker-drivin g gearing located at or near the conjunction of right lines produced axially through the vertical pivot of the stacker and the shaft of the cylinder, respectively, and a drive-shaft for the gearing formingan approximate continuation of the cylinder-shaft.

In a more restricted sense the invention also resides in the details of construction and combinations of parts hereinafter set forth and claimed, whereby the broad idea is perfected in various particulars.

In the drawings forming part of this specification, Figure 1 is a side elevation of the rear end of a sheller-frame and the front end of a stacker, showing the stacker-gearing in operative relation thereto. Fig. 2 is a rear elevation of the stackergearing enlarged. Fig. 3 is a plan of the stacker-gearing. Fig. 4is a vertical section on line X in Fig. 2. Fig. 5 is a plan of a stacker, the gearing therefor, and so much of a sheller as is needed to explain the relation of the gearing to the sheller.

In constructing a stacker and connecting it with a sheller in accordance with my invention a pair of brackets 2 are fastened one to the rear end of each of the lower sills 1 of the sheller-frame. Bars 3 are connected one with each of the brackets 2 and are extended upward, backward, and inward to the vicinity of the horizontal plane in which the shaft of the cylinder of the sheller lies. A horizontal plate 4 is made with downwardextending lugs 6, and its rear portion is arcformed, as shown at 5, and arc-slotted, as shown at 5 in Fig. 3. The plate 4 is mounted horizontally on the upper ends of bars 3 by means of bolts that extend through the bars and through the lugs 6 of the plate. A swingable frame consisting of collar 7, arms 8, extension 9, and brackets 10, and preferably integral, is journaled to swing horizontally on plate 4. A shaft 11 (seen only in Fig. 4) extends vertically through the plate and through the collar 7 of the swingable frame, and it has gear-wheels l2 and 13 on its upper and lower ends, respectively. Ahorizontal shaft 14 is journaled in brackets 10 of the swingable frame. It has between its bearings a gear-wheel 15, which meshes with wheel 12, and one of its ends projects beyond its bearing and is provided with a pulley 16. The extension 9 of the swingable frame is provided with a bolt 1 9, which extends through slot 5 of the plate 4 and through a hole in the extension 9, and such bolt provides for holding the frame in different positions with relation to the fixed plate 4. The upper half of a'boxing is secured to the front end of plate 4:, as shown at 21, and the under half 22 is secured to the upper half. A gear-wheel 20 has an elongated hub which journals in the bearing formed by parts 21 and 22, and it meshes with wheel 13. A collar23, formed on the end of the hub of wheel 20, aids in. holding such wheel from longitudinal motion.

The wheel 20 and its hub have a longitudinal aperture prismatic in cross-sectional conformation, into which the rear end of a prismatic drive-shaft 24 extends. The shaft 24 is held at its forward end in a collar 26, which is fastened onto the rear end of the sheller-shaft 27, and its fittings at both ends are sufficiently loose to give it a slight tunibling-shaft action and thereby obviate the necessity of accurate alinement between the wheel 20 and the sheller-shaft.

Brace-rods 25 extend from plate 4 back to the sheller-frame, as shown in Fig. 5, and they aid in holding the gearing in proper position.

A bracket 29 is fastened to the bolster 28 of the sheller-truck, and it projects rearward therefrom to an extent sufficient to bring its rear end under the vertical shaft 11 of the stacker-driving gearin A yoke 30 pivots in a vertical bore in the rear end of bracket 29, and it carries the front end of the stackertrough 31. The rear swinging end of the stacker-trough is sustained in an elevated position by means of brace-bars 18, which connect one with each side of the trough and with an end of arm 8. The drag-belt 32 of the stacker-trough runs around a live-pulley in the rear elevated end of the trough and around an idler in the forward end. The shaft of the livepulley is supplied with a drive-pulley 36, (seen only in Fig. 5,) and a belt 17 conveys motion from pulley 1b of the gearing to pulley 36 of the stacker.

The hopper 33 of the stacker-trough rests under the discharge-spout 35 of the screenframe 3a of the sheller and receives the cobs as they pass from the sheller.

In Fig. 5 the casing of the cylinder of the thresher, of which cylinder 27 is the shaft, is shown in part at 37.

In operation the shaft 24 turns with the shaft 27 and imparts motion to wheel 20. \Vheel 20 turns wheels 13 and 12, which transmit motion to wheel 15 and pulley 16, and the transmission is completed by belt 17 and pulley 3G. The arms 8 of the swingable frame are connected with the stacker-trough in a manner to compel the frame to swing with the trough and thereby keep the belt-pulley 16 in proper relation to the pulley 36 of the trough, and, 011 the other hand, the clamping of the swingable frame onto the fixed plate 4 by means of bolt 19 tends to hold the stacker against swinging motion. The shaft 11 is concentric with the pivot of the swingable frame, and so the swinging motion of the frame does not affect the action of the gearing.

The advantages of the invention lie in its simplicity, directness of application of force, and desirability of location of the gearing. Motion is transmitted from the sheller in a very simple and direct manner, and the gearing is well up out of the way of everything that might tend to interfere wit-l1 its operation.
